• Portable light weight handheld meter
• Lcd display
• Alarm for high co2 level
• Auto calibration
• Monitoring & analysis allows continuous monitoring of co2, rh & temperature level. Data output to pc every 2 seconds.
• Multiple measurement displays at once- co2, temperature, and relative humidity readings are all shown on the lcd display at the same time
• Normal/ max/ min/ average (15mins/ 8hrs) mode- it can show not only the normal, maximum and minimum co2 readings but also the weighted average co2 readings in the past 15mins (stel mode) and 8 hours (twa mode).
• Audible co2 sound- the alarm beeps when the co2 level exceeds the preset value. The alarm threshold is adjustable.
• Accuracy: co2: 0~2000ppm, ±50ppm or ±5% of the reading; above 2000ppm, ±10% of the reading
